Designed for undergraduate computer science and engineering students, Networks for Computer Scientists and Engineers by Youlu Zheng and Shakil Akhtar includes both fundamental theory and modern technologies. It covers LAN, WAN, and high-speed networking technologies; OSI seven layers; data communications; network performance and programming; and management and security. Each chapter contains problem sets and up-to-date references to current World Wide Web sites. This data communications and networks textbook includes numerous figures, examples, summaries, review questions, a glossary, and references. Answers to the review questions are provided in the accompanying instructor's manual. A progressive and cumulative approach to presenting material provides students with a better understanding of complex concepts as each chapter effectively builds on previous information. One of the unique and innovative features of Networks for Computer Scientists and Engineers is its instructor's manual and CD, which provide software development projects and step-by-step instructions for constructing a cost-effective prototype network lab, using resources available to most four-year colleges. The projects are not merely samples but complete software packages with real applications that have been thoroughly tested by professors and students at several universities. The CD-ROM contains lab materials, the LINUX operating system, and program source codes for the software projects. Since today's service-oriented network environment requires supervisor privilege for all management and security functions, this cost-effective prototype not only demonstrates how different protocols and components are integrated into a heterogeneous network, but also provides an ideal environment for trouble-shooting and experimental network management. Networks for Computer Scientists and Engineers, the accompanying software projects, and the prototype lab actively engage students in the learning process and provide opportunities for critical thinking, problem solving, and creativity in a controlled real-world setting.
